WRENCH POLE. 1

Application filed September'l, 1922. Serial No. 585,738.

To all whom it may concern.

Be it known that I, Lonnuzo JACOB S'roNnR, a citizen of the UnitedStates, and resident of Tulsa, in the county of Tulsa and State ofOklahoma, have invented certain new and useful Improvements in renchPoles, of which the following is a specification.

This invention relates to wrench poles especially adapted for use indrilling wells.

The wrench poles now in use are very crudely constructed, being formedprincipally from saplings tied up in the derrick with rope about fortyfeet from the derrick floor and the wrench balancing weights are blocksof wood tied to the poles with rope making it difficult to obtain theright balance.

Therefore, an important object of this invention is to provide a wrenchpole in the nature of a steel I-beam to which a balance weight isslidably connected and which is held in the proper position forbalancing the wrench suspended from the other end of the beam.

A further object is to provide a wrench pole of the class describedwhich may be conveniently attached, which is durable in use and cheap tomanufacture.

Other objects and advantages will be apparent during the course of thefollowing description.

In the accompanying drawing forming a part of this application and inwhich like numerals are employed to designate like parts throughout thesame,

Figure 1 is a fragmentary perspective of the improved wrench poleapplied.

Figure 2 is an end elevation of the same.

Figure 3 is a perspective of the balancing Weight embodied in theinvention.

In the drawing wherein for the purpose of illustration is shown apreferred embodiment of the invention, the numeral 5 generallydesignates an I-beam formed from steel or other suitable material andwhich is connected adjacent one end to an attaching hanger 6 the upperportion of which is,

formed with a hook 7 adapted for engaging one of the beams 8 of thederrick. The hanger 6 is connected to the beam 5 through the medium of aU-shaped clevisor attaching member 10 the terminal portions of which areformed with eyes 11 for the reception of a fastening bolt 12. Thefastening bolt 12 is, of course, extended through the web of the I-beamand pivotally connects the coupling 1O tothe beam.

That end ofthe beam 5 adjacent the bolt 12 is provided with a U-shapedhanger 13 from which a flexible wrench supporting element 14 issuspended and, as illustrated in Figure 1, a wrench 15 is connected tothe lower portion of the member 1%.

Figure 1 illustrates that a balancing weight is formed with alongitudinallly extending T-shaped groove 22 for the reception of theupper flange and the web of the beam. A holding bolt 25 is passedthrough an opening 26 in the weight and through any one of a series ofopenings 28 1 in the web of the beam. By means of the spaced openings 28and the bolt 25 the balancing weight may be readily and convenientlyadjusted for use in connection with wrenches of various weights.

As the result of extensive use of the improved wrench pole the same hasbeen found to be extremely reliable, durable and elficient. The wrenchwhen not in use lays flat on the derrick floor and may be readily raisedto operative position on account of being prop erly balanced Also, awrench pole constructed in accordance with this invention may beconveniently installed and adjusted for use under a variety ofconditions.

I claim 1. A wrench pole for use in oil and gas well operationscomprising an I-beam, a wrench supporting member connected to one endofthe beam, the other end of the beam being provided'with a seriesofopenings, and a balance weight having a T-shaped groove receiving theupper flange and the web of said beam, said. weight being provided witha fastening bolt selectively extending through one of'said openingswhere y to ad justably connect the weight to the beam whereby to balancethe wrench.

2. A wrench pole comprising an I-beam, a balance weight having a groovereceiving said. beam, means adjustably connecting the weight to thebeam, a coupling member connected tothe beam between its ends, a hangerconnected to said coupling, a U-shaped connecting member havingconnection with one end of said beam, and'a flexible wrench supportingmember suspended from said LL shaped connectin member.

LOREN O JACOB STONER.
